Up to 1.5GHz FSBs, apparently

The chipset will run the frontside bus at up to 1500MHz, leaked presentation slides posted on a DailyTech report show, while the PCI Express bus can run at up to 25 per cent above standard speed - the better for CrossFire cards that connect solely across the PCI-E bus.

Crucially, the memory clock is independent of the FSB and CPU clock frequencies, allowing users to clock each to their maximum. A separate slide indicates the chipset will support DDR 3 SDRAM.

According to the report, RD600 will support three x16 PCI Express connectors - two for graphics and the third for a graphics card doubling up as a physics processor. Boards based on the part will retail for around $150, the report adds. ®
